I would have hoped that the subject of the superior/inferior quality of the A6M would have appeared on the 'Greatest aviation myth this site "de-bunked"' thread. For anyone who has not figured this out, the answers to the following questions should help out.
As of the effective 1941 service entry date of the A6M:
How many in-service aircraft designed in the late-1930s carried armour before WWII started?
How many in-service aircraft designed in the late-1930s carried self-sealing fuel tanks before WWII started?
How many in-service aircraft designed in the late-1930s were more heavily armed?
How many in-service aircraft designed in the late-1930s were faster?
How many in-service aircraft designed in the late-1930s had a longer effective radius of operations?
How many in-service aircraft designed in the late-1930s had a better climb rate?

How many in-service aircraft designed in the late-1930s could turn better?
How many in-service aircraft designed in the late-1930s could roll better?
How many in-service aircraft designed in the late-1930s could dive better?
How many in-service aircraft designed in the late-1930s were more reliable?
How many in-service aircraft designed in the late-1930s were more maintainable?
How many in-service aircraft designed in the late-1930s were more
capable at carrier operations?
How many in-service aircraft designed in the late-1930s had better multi-role capability?
I suggest that anyone interested make a chart with these questions on the left as rows, different aircraft types across the top as columns, and place check marks in the appropriate boxes. Total them up at the bottom and see what you get.
